We all love to chat using facebook, google talk... etc but just keep an eye on this:

A new computer virus, known as Steckt.Evl, is making its way around the Internet is being spread by cloaking itself as a harmless looking link being sent as an instant Facebook chat message. If your friend’s computer is infected, this worm will automatically use their Facebook account to send you a link in a chat window so don’t assume that just because it is a link a friend sent it is safe to click. Verify directly with your friends that they actually sent you any links that pop-up in your Facebook chat window before clicking them. The pop-up window, used for person-to-person chat, pops up with a message from a ‘friend’ which links to an innnocent looking website. The virus instantly disables and removes anti-virus software, then spreads itself by opening chat windows on the Facebook friends of the user.
